    Abstract: Chromic acid production is now simplified in a process using the concentrated dichromate typically available at an intermediate stage when chromic acid is produced from chrome ore. In the process, the dichromate is treated in a three-compartment cell as, for example, after removal of the sulfate or carbonate salt evolved in the overall production process. The dichromate feed enters the center compartment of the three-compartment cell and then flows through a porous diaphragm to the anode compartment of the cell and is electrolyzed at elevated current density. Depleted feed solution may be withdrawn from the center compartment and recirculated for reuse. Concentrated, water-white alkali product is produced in the cathode compartment. The anolyte from the cell, rich in chromic acid, can be concentrated, cooled, and the chromic acid recovered. Liquid removed from chromic acid recovery can be recirculated for subsequent electrolysis, as by combination with the feed. Both alkali product and anolyte chromic acid can be produced at enhanced current efficiency.

    Abstract: An alkali metal battery has an alkali metal anode such as lithium in an organic anolyte and a cathode in an aqueous catholyte. An ion conductive diaphragm allows ions to migrate between the anolyte and the catholyte while limiting the transport of water from the catholyte to the anolyte.In a preferred embodiment, the ion conductive diaphragm is nonporous so that there is no transport of water ion to the anolyte.The battery is particularly useful for long durations of up to a week or longer in seawater.

    Abstract: A lithium-water battery provides reliable power for long durations in the ocean at temperatures down to 0.degree. C. and pressures up to 680 atmospheres (10,000 psi) without the need for mechanical pumps or valves to admit reactant water from the ocean into the battery or to maintain a circulating electrolytic solution in the battery. The battery has a natural circulation, alkaline, aqueous electrolyte contained in the housing with a lithium anode and a cathode disposed in the electrolytic solution. A hydrophilic cation exchange membrane attached to the housing is disposed between the electrolytic solution and the ocean environment surrounding the battery for retaining the hydroxyl ions in the alkaline electrolytic solution while admitting water into the solution from the environment.Advantageously, a low power lithium-water battery can provide several watts at about 1.4-1.5 volts for up to a year or more anywhere in the ocean.

    Abstract: Chromic acid is now efficiently prepared in a process using dichromate, such as the dichromate typically available as an intermediate in the chromic acid production from chrome ore. In the process, the dichromate is introduced into the center compartment of a three-compartment electrolytic cell and dichromate-containing center compartment electrolyte flows through a porous diaphragm into the anode compartment of the cell. Electrolyte is introduced to the cell cathode compartment which is separated from the center compartment by a substantially hydraulically impermeable cation-exchange membrane means. During electrolysis, chromic acid is prepared in the anolyte and alkali product is produced in the catholyte.

    Abstract: A surfactant is present in an aqeuous alkaline electrolyte of a consumable metal anode electrochemical cell in a concentration sufficient to substantially reduce both the surface tension of the electrolyte and the rate of the parasitic corrosion reaction occurring between the electrolyte and the anode. The surfactant is useful in minimizing the harmful side effects, such as increased heat generation, anode consumption without producing useful energy and increased hydrogen gas production rates, such as are associated with the parasitic corrosion reaction experienced in such electrochemical cells.
